vLETTER-FILE.

SPECIFICATION forming part of Letters Patent No. 510,350, dated December 5, 1893.

Application led March 30, 1893. Serial No. 468,307. (No model.)

To all whom it may concern,.-

Be it known that I, JOHN LOCHMANN, a citizen of the United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in Letter-Files, of which the following is a specification.

This inventionl relates to letter files and the object of the invention is to provide a letter le which is strong and durable and readily manufactured as set forth in the following specification and claims and illustrated in the accompanying drawings in which- Figure lis a transverse vertical section in the plane :I: Fig. 2. Fig. 2 is a plan view partly in section in the planeyy Fig. 1. Fig. 3 is a transverse vertical section of a modification the plane of section bein gindicated by the line Fig. 4. Fig. 4 is a horizontal section in the plane zz Fig. 3. Fig. 5 is a transverse vertical section of another modification, the plane of section being indicated by the line y y Fig. 6. Fig. 6 is a horizontal section in the plane z z Fig. 5.

In the drawings the letter A designates the front of the letter file and Bis the back having a suitable cover or closing tlap O. The bottom D is bent or creased at E E to form gussets in the usual way. The sides G are also creased to form gussets I aswell known. Into the gussets E Iare placed the partitions K. Each of these partitions is provided with one or more end flaps or Wings L secured to the sides G. These flaps or wingsl L are readily formed by securing to the partition K a strip M of muslin or equivalent material which extends beyond the partition so that its projecting end will form the flap L. In the example shown in Figs. 3 and 4 the strip Mis secured to one side of the partition K and its end flap L is fastened to the inner face of one of the side gussets I. Of course two strips M may be provided and one of them attached to one and the other to the opposite side of the partition.

In the example shown in Figs. 5 and 6 the strip M is lapped over the top edge of the partition K and pasted or fastened in place. The ends of the strip which project beyond the ends of the partition. form flaps L which are bent to one side and fastened tothe side gussets I.

In the example shown 'in Figs. l and 2 the strip M is lapped over the top edge of the partition K and its ends which project beyond the edges of the partition, are cut at the top so as to form two aps L one of which is fastened to one and the other to the opposite side of the side gusset I. By these means I am enabled to secure the partitions K irmly in position.

What I claim as new, and desire to secure by Letters Patent, is-

l. A letter file having a partition K" provided with a strip M secured to its side and forming a flap L adapted to be secured to the side gusset I substantially as described.

2. A letter le having a partition provided with a protecting strip lapped over `the top edge of the partition, the ends of the strip being left projecting to form flaps, said flaps being secured to the side gussets substantially as described.

3. A letter le having a partition provided with a protecting strip lapped over the top edge of the partition, the ends of the strip be ing left projecting beyond the partition and being cut or separated to form oppositely extending fiaps at the partition edges, said [laps being secured to the side gussets su bstantially as described.

In testimony whereof I have -hereunto set my hand in the presence of two subscribing witnesses.

JOHN LOOHMANN.
